T0 all whom t may concern: g

Be it known that I, PHILIP HARTMAN, a citij zen of the United States, residingatEhren-i feld, inthecounty of Cambria and State ofl Pennsylvania,have invented certain new and f; useful Improvements in Hauling and Controlling Mechanism for Cars or Vehicles, ofi which the following is a specficatiomrefer-,f ence being had therein to the'accompanying drawings. E

This invention relates to an improved mechanism for cars, wagons, vehicles, dac. it relat-g ing more particularly todevices of the sorti i at the top of the incline which drum is utilasive accidents are constantly occurring where used in controlling, manipulating, and propel-l ling cars which are arranged to move up and; downinclined planes, such as are employedg in connection with coal mines for letting loaded cars down from the mouths of the pits toiE the tipple houses', or weighing scalesgand then haulingthem, after being emptied, back tof; the top ofthe incline and close to thel p itl mouth again. Heretoforeusemas' generally; ybeen made, for this purpose of ropes, or cablesi hitched directly tothe rear end of the train, ior trip, of loaded cars, and at the other-g ,end hitched to the front end of the tripof yempty cars, the intermediate partof therope; or cable passing around the w-inding drum:

ized to regulate thel escape of theropedownward, and the winding of it as it comes up. It is well known that dangerous and expenuse is made of devices ofthe sort last referred to. The holder being at the upper end-of -eachtripf the'entijreweight of it is of course below the holder, thatis-below the point where the rope or cable is connected.

One of the objects of the present invention isto overcome thisdanger and avoid entirelyv the possibility of the cars at the lower end of the trip from becoming detached from those above.

Another object lis to provide an automatically acting device for engaging with and disengaging itself from a trip of such cars, so that the labor and trouble incident to the operation of fastening at the top of the inf cline, and the unfastening at the bottom shalli be done away with. l

There are other objects aimed at, and other .features of construction and arrangement sented by D and the other by D.'

bodying my improvements, it rshowing also,

somewhat con ventionally, parts of an inclined roadway of the general sort hereinbefore re ,ferred to. Fig2 is a plan view of the same. Fig. S is a side view ofl the car haul on a larger scale. Fig. 4 is a top view of the same. Fig. A

'5 is a cross section on line of Fig. 4. Fig, 6 is a section on y,line fy-y of Fig. 4. Fig. 7 is a section of one ofthe wheels and axles enlarged. Fig. 8 is-a section similar to that in Fig. 5, but showing the truck when running on the main track rails.

In thedrawings A A represent the rails of a track adapted tohave cars ittedto it such as my invention can be employed with.

I have selected for illustration parts of the apparatus used atthe mouth of a coal mine,

including parts of the track on the hill side or incline, and parts of those at the tipple house or placewhere the weighing andun' loading are accomplished: lbut I wish it distinctly understood that I do not limit myself to ause of the invention in connection with such amine, or with the incline shown or with any particular unloading apparatus, -inasmuch as the essential parts of the invention can be applied to any of several uses more or less differing from that mentioned an'd illustrated.-

Somewhat near the track rails A A, and substantially parallel therewith there are placed the rails A A', of another track this being the arrangement generally used in coal mines of this sort, one of the tracks being used for letting down a trip of loaded cars, and the other being used at the same time for hauling up a trip of empties.

B indicates, generally, a cable or rope used for letting the loads down, and which may be of any of the sorts now in use. And with it use can be made of any preferred mechanism at C .for controlling thel movements of the rope, such as a friction drum, dac. Y

To the ends'of the rope or vcable B I attach two of my car hauls, one of which is repreduplicates of each other. Each consists essentially of a body or main frame and a suitable number (preferably four) wheels. The body or frame may be made of cast metal, wrought metal, or wood, or other suitable material. As shown in the drawings it has a top d, end walls d', d2, side walls d3, and one or more central webs or bearing plates (Z4. From the said central parts there extend outward axles E, E, and upon these are mounted four wheels respectively indicated by F. Each wheel is formed with two grooves or guide ways f and f adapted to tit over and ride upon the top of the track rails A or A and A2 respectively.

At G there is a central passage through the wheel axially, for the reception of an axle or shaft E, and at the outer ends these apertures G terminate in expanded chambers as at Gr.

H indicates a collar secured to the outer end of each axle and lying Within one of the chambers G. The chamber is somewhat longer than the thickness of the collar so that the wheel can have a limited play out and in along the axle for a purpose to be described. The wheels are self piling, each being formed with a chamber or cavity at I, andthere is a cap t' secured to the outer face of the wheel opposite to the chamber G. The cap has an orilice at t" through which oil can be readily introduced to the oil cavity, and from this cavity it wi`l distribute itsell:` gradually tothe interior of the axle passage and collar chamber at G, G for the collar H being merely used as a stop for said wheels, it lits loosely enough to allow the oil to readily gain access to the oil cavity.

By examining Fig. 5 it will be seen that the inner part of the wheel is extended inward as far as possible so as to provide a long bearing for it on the axle, the metal at the said end being reduced somewhat. The width of the frame D is such that it can be dropped between the rails of the tracks A or A', that is, the outside width ot the frame or body is about equal to or a little less than the inside width of either track. And the wheels are so mounted that they can slip inward till the distance between their outer faces shall be less than that between the inner sides of the track rails, and yet they can when necessary slip outward far enough to have the grooves f tit ou the track rails A or A.

At the foot of the incline or at other suitable place a mechanism is arranged for throwing the car haul devices D and D out of the aths of the vehicles which4 are propelled or controlled thereby.

In the drawings I have shown at A2 a section of track composed of a wider part a, anarrower part ct and an intermediate tapering part a2, the ends of the wider part terminating at a3, a3. And by examining Fig. l it will be seen that the latter end parts are elevated somewhat above the level of the top surfaces of the main track rails A and A. The narrower part a of this supplemental track may be of any desired length, but ordinarily it will not need to be more than about twice the length of the car haul D. And at the end of it there can be a stop or bumper as at J if desired. The ends a3 as are at adistance apart equal to the distance between the grooves f' oftwo opposite wheels F.

At A4 is a section of track uponwhich the cars run to be dumped, after they are disengaged from the truck.

The cable B is secured to the end walls d2 of the frames.

The manner of?4 operating a mechanism of my improved sort will be readily understood from the drawings, and the description given above. In Figs. l and 2 a trip of loaded cars is shown as passing down the left hand track A, and a trip of empties is shown as passing up. The car haul D is situated below the loaded cars and ot' course prevents them from moving rapidly down. The front car L ot' the trip rests against the hauling device and pushes it before it as it travels down; and at the same time the haul D is being drawn toward the drum at the top of the i11- cline and is therefore carrying upward the trip of empties. As soon as the haul D reaches the supplemental track A2 the wheels E engage with the ends a3 of that track, the inner groovesf fitting it. And as this innerorsupplemental track is slightly elevated at the ends a2 the rst result is tolift the haul D up a little so as to get its wheels F F entirely clear of the outer track A. Then, as the cars L continue to move down and push the haul D ahead of them, the wheelsF of the latter (after getting free of track A) are drawn in by the tapering part of the track A2 until said wheels Flare entirely inside ot' track rails A. And a still further forward movement of cars Lcarries the haul D onward to a narrower and lower part a of the track A2, and after it is fully on this part of the track the body or frame D has dropped far enough to permit the cars L to move over the haul D, on track A4 and on to the place for weighing the tippling. After the cars have been emptied they are pushed by hand or otherwise back, to a point such that they shall be ahead of the haul D, ready for ascending the incline. When the movement of the rope or cable B is reversed the haul D is drawn back from the inner or supplemental track A2, and as it passes over the ends a2 of the said track its wheels F F are so adjusted in position automatically that they will again rest upon and move along the track rails A. As they rise up from the depressed part a of the track A2 they carry the haul D up far enough to again lie behind the rear car L, and then any further strain upon the rope causes the haul to propel the cars up the incline until the top level is reached, where they are detached and again carried into the mine.
